Fexlamose (formerly known as AER-01) is an experimental inhaled small-molecule drug developed by Aer Therapeutics to treat muco-obstructive lung diseases like COPD (Chronic Obstructive Pulmonary Disease) and asthma. It is a thiol-modified carbohydrate designed to break down mucus plugs in the airways

How it Works

Mechanism: Fexlamose acts as a mucolytic by cleaving the disulfide bonds in mucus, thinning the thick secretions that block airways.
The Problem It Targets: While many respiratory drugs manage inflammation or relax airway muscles, currently no approved treatments directly tackle mucus plugs, which are a major cause of breathing difficulties in COPD.
Delivery: It is administered as an inhalation solution (or potentially a dry powder) directly into the lungs.
Current Clinical Status
Fexlamose is an investigational drug and is not yet approved for public use or commercial prescription.
Clinical Trials: It is undergoing Phase 2a clinical studies (such as the AER-01-002 trial) to evaluate its safety, tolerability, and efficacy in adults with moderate to severe COPD.
Study Design: These trials utilize specialized CT mucus plug scoring to identify patients who are most likely to benefit from the therapy.
